16.3.2 Layer II Coding The Layer II coder provides a higher compression rate by making some relatively minor modifications to the Layer I coding scheme.

STMicroelectronics has announced an MPEG layer 3 audio decoder chip that also includes an embedded ADPCM (adaptive differential pulse code modulation) codec to allow voice recording and playback.

Using a psychoacoustic technique called binaural cue coding, MP3 Surround captures the spatial image information of multi-channel sound. This method is critical in achieving the compact file size ...

Using MP3-like code, engineers spot hospital alarm 'masking' Date: March 16, 2017 Source: University at Buffalo Summary: The failure of hospital caregivers to respond to medical alerts is often ...

Principally, we will examine the different MPEG standards for audio compression. These include MPEG Layer I, Layer II, Layer III (or mp3 ) and the Advanced Audio Coding Standard. As with other ...
